Czechoslovak exile souvenir sheets
1939–1945
Commemorative sheets made abroad during the war and just after it: for the Czecho-Slovak pavilion at the New York World's Fair of 1939 and 1940, for the exile government's stamp exhibition in London in 1943, and for the liberation celebrations in Brussels in 1945. They were souvenirs and propaganda rather than postage stamps, and no stamp catalogue lists them, so they are entered here by hand, numbered E1 onwards, without value bands.
